[Knowledge of the Assistance Bioethics Committee (ABC) between the general hospital health professionals].

To show hospital health professionals' knowledge on ABC. Observational, descriptive, transversal and analytical research using questionnaires designed ad hoc. Comparative statistical analysis applying Ji-square by Pearson and Fisher tests. Binary logistic regression model to determine the odd ratios (O.R) having education level and sex as independent variables. A 4% accuracy was accepted, as well as a confidence Interval of 95% and a p value inferior to 0.05. The data was processed by IBM SPSS Statistics v.20 software. Required sample of 351 professionals (108 doctors and other related graduate; 144 nurses and 99 clinical assistants (TCAE)). 276 participants (78,6%; IC95%: 74,0-82,2); of which 84 doctors (77,8%; IC95%: 68,8-85,2); 120 nurses (83,3%; IC95%: 76,2-89,0) y 71 TCAE (71,7%; IC95%: 61,7-80,3), predominantly women (194, 70,3%). 228 (82,6%) were aware of the existence of ABC. Both doctors and nurses had more knowledge of ABC than clinical assistants (p 0,0001 for both), however there was not significative difference between doctors and nurses (p=0,836; OR:0,901; IC95%: 0,334-2,228). 124 (45,1%) knew the functions of ABC, with doctors displaying more knownledge than both nurses and clinical assistants (p=0,002 and p 0,0001 respectively) and nurses showing more familiarity than clinical assistants (p=0,008). 129(47,6%) communicated ethical conflicts, showing no significative difference between doctors and nurses (p=0,119). However, clinical assistants displayed different behabiour than the other two groups in this regard (p 0,0001 and p=0,001 respectively). Of all, 47 (22,4%) communicated they had ethical conflicts regarding the beginning and end of life. The knowledge on the existence of the ABC is high, however there is poor knowledge around its functions. Among health professionals, doctors and nurses know him better than TCAE. Matters related with the beginning and end of life cause most of ethical conflicts.
